I just encountered this question. Here's my answer:
Given:
3 kids
product of their ages is 72.
Youngest child.
The youngest child means that all three kids have different ages.
We need to factor 72. Let us use prime factorization.
72 ÷ 2 = 36
36 ÷ 2 = 18
18 ÷ 2 = 9
9 ÷ 3 = 3
3 ÷ 3 = 1
1 x 2 x 2 x 2 x 3 x 3 = 72
Based on the factors we can assume the following ages:
2 x 4 x 9 = 72
3 x 4 x 6 = 72
1 x 8 x 9 = 72 I prefer this age combination.
1 x 3 x 24 = 72
<span>1 x 4 x 18 = 72</span>
Answer:
1,877
Step-by-step explanation:
845/13 = 65
65 x 32 = 2,080
2,080 - 203 = 1,877
We can find the side length of square 3 by dividing by 4, which is 9.
Then, we find the side length of square 2 by dividing it by 4, which is 12.
To find the AREA of square 1, we do a^2+b^2=c^2. This is basically adding up area of square 1 and square 2 to get square 3.
a^2+b^2=c^2
9^2+12^2=c^2
81+144=225
So the area is 225 units.
Answer:
a

2/15 sorry if it’s wrong all I did was just divide both of them
